Toal l tviwmz'tm'dy concern) I Be it known that I, DANIEL L. MoFEc 4 GANS, a citizen of the United States, and a resident of'Newark', county of Essex, and State of New Jersey, have invented certain new and useful Improvements in Door- Stops, of which'the following is a specification.

' i This invention relates toa door stop that is of the type that'holds'the door open un der normal drafts and pressures, but which can be closed by a positive pushing'or jerking of the door toward a closed position.

. The invention relates to a devicei of this kind which requires no fixturein' the floor, and is therefore well adapted for use for doors tliatopen into hallways, and is partic ularly adapted for use in institutions such as schools, in that the door can be held in an open position in a positive manner, but if it is shut there is nothing in the floor to act as an obstruction.

The invention is further designed to provide a door stop which is easy in its action and substantially noiseless, being adapted to run light enough so as not to interfere with the action of the ordinary door closer or door check.

The invention further relates to certain details of. construction which will be more fully described hereinafter and finally embodied in the claims.

The invention is illustrated in the accompanying drawing, in which Figure 1 is a top view of the door stop, the door casing and the door being shown in dotted outline. Fig. 2 is a side view of the device shown in Fig. 1. Fig. 3 is an enlarged side view of the door stop, showing the parts in alinement. Fig. 4: is a side view of the end of the rod with a swiveled member shown in section to more clearly illustrate the construction. Fig. 5 is a perspective view showing the casing of the swiveled member and also the latch detached therefrom, and Fig. 6 is a section on line 6-6 in Fig. 3 to illustrate the shape of the preferred form of rod.

To more clearly illustrate the invention I will describe one member as being affixed to the door casing and the other member as be ing affixed to the door, but it will be understood that this arrangement can be reversed, if found desirable or expedient.

In the drawing 10 is the door frame and 11 is the door. The rod 12 is fastened at one end so that it is pivotally supported on the door, the form of fastening shown consisting of a plate 13, which includes a bracket 14, and a pivot pin- 15 fastens the rod to the bracket. The rodispreferably flat, although other shapes of rods can be used, and the lower face is provided, near its outer end, with a ribhaving an inclinedv part 16, adjacent to which is a recessed part 17 .v At the end of the recessed portion 17 of the rib is a stop 18. The member that is at:

't achedto the door casing is preferably 'securedthereto by being swiveled, and I therefore identify this member by calling it the swiveledmember. p The swivel'ed member includes a cupshaped casing 19, which has a top plate 20 thereon fastened in a suitable manner, such as by the screws 21, the top plate 20 also being pivotally attached to a supporting plate 22 by a pin 23, a washer 24 being usually insorted to make the relative rotation of the parts easy. The supporting plate 22 is secured by any suitable means to the door casing, the holes 25 (Fig. 1) being illustrated as one form to permit such attachment.

The recess 26 in the cup-shaped member forms a chamber for the reception of a spring 27, which abuts on the end of the chamber and also at its other end on the latch 28. The side walls 29 extend up to form guides for the sides of the rod 12, the end walls being cut away, as at 30, to provide a passage for such rod and being notched, as at 31, to provide a space for the entrance of the inclined portion 16 and the recessed portion 17, the part in which the inclined part 16 and the recess 17 is placed being in the form of a ridge which extends beyond the bottom face of the rod. I prefer to chainfer the rear edge of the inclined portion, as at 32, and the corner of the latch which engages it is preferably chamfered or the recessed portion 17 and also the top face of the latch 28, are substantially flat and of considerable area so that the frictional engagement is such as to hold the parts so that an element being held, such as a door, is

not susceptible to ordinary pressure, such as a draft or a slight pull, but at the same time permits a smooth and easy operation of the door or the like when it is positively swung to the position it is toioccupy, particularly when the parts are in the position shown in Fig. 4, that is, at the extreme outward position. All that needs to be operated is the door and there are no latches tobe released manually other than the release that results from a positive and vigorous operation of the rod 12.

The device is'substantial and it is practically noiseless, and the construction permits of its use adjacent to the top edge of a door, the swiveled member being attached plate thereon, the top plate being swiveled to the supporting plate, the cup-shaped 'inember having a cut away portion at the top, a spring in the cup-shaped member, a

latch plate floating on the spring, a rod pivoted at one end and sliding in the cut away portion and in contact with the latch, the, rod having a recessed part at itsendtoreceive the latch.

2. A door stop comprising a supportingplate, a cup-shaped member, a top plate on the cup-shaped member and swiveled to the supporting plate,'the walls at the top of the cup-shaped member being cut away to form a passage and notched at the bottom of the passage, a spring in the cup-shaped mem- V ber, a flat latch floating on the spring, a rod sliding in the passage and. having a rib with a recessed part and having astop on the end, the recessed part being adapted to receive the latch, the notch being adapted to receive the rib so that the latch can enter therecess of the rib;

In testimony that I claim the foregoing, I

have hereto set my hand, this 17th day of February, 1920. e v
